gut-brain axis

Small plastic particulates can induce inflammatory responses in the gut and brain, but removing them reverses this damage.

The effect appears to be mediated by a gut-secreted peptide that signals to neurons in the brain that modulate the response to mechanical vibrations.

Renewing the aging gut microbiome holds promise for preventing inflammatory brain and eye degeneration.

Experiments in animals and observations in humans suggest that the amount of proline circulating in one’s plasma has a strong association with depression severity.

Microbes in the gut influence the death of support cells in the brain by producing isoamylamine, a study suggests.

A study shows that a molecule produced by intestinal microbes can enter the brain and that its presence is also associated with altered brain connectivity.

Research in mice and flies suggests that bacteriophages, including those found in dairy foods, may have an influence on an animals’ ability to learn and remember information.

Signals from sweeteners and sugars are relayed from the gut to the brain by different neural pathways, a new study concludes.

Intestinal bacteria contribute to the effect of stimulating environments on the brain’s ability to adapt, a study concludes.

The unbalanced gut flora present in some people with autism is not a driver of the condition but rather a consequence of eating behaviors characteristic of the condition, a new study claims.

Physical activity, independent of diet, shifts the composition of bacteria in the intestines, spurring researchers to search for species that might provide benefits akin to working out.

The gut microbiome has been linked to depression, schizophrenia, and other neurological conditions, but it’s not yet clear whether the relationship is causal.

Johns Hopkins’s Ted Dawson discusses his lab’s demonstration that misfolded α-synuclein can move from the stomach to the brain and cause physical and cognitive symptoms.

The researchers who made the discovery suggest the signaling may form a sixth sense.

Normal brain function may have evolved to depend on gut microbes and their metabolites.
